648FX-A Motherboard doesn't seem to work with P4 3.0Ghz

I have a 648FX-A working with a P4 2.66Ghz and recently bought a P4 3.0Ghz cpu so i could have a bit more out of the board. The problems is that it doesn't work with the 3.0 processor, the systems boots but nothing appears on screen, when i switch back it does ok. I recently bought a new psu too holding 500w, honestly i don't understand why this is happening. I've already upgraded to the latest bios to (1.0c) and the problem remains, reseted bios.. Thanks for any help

There will be a jumper on the motherboard that you can pull/move that will reset the bios. another option is to unplug the power and pull the battery out of the board (looks like a standard watch battery). wait 15-30 seconds and reinsert the battery. turn the computer on, if the issue persists after this solution try again but wait longer after removing battery. if that doesnt work its possible you have damaged the computer.

I'm not real sure that your problem is the motherboard. Have you checked to make sure that mute isn't on, and looked inside sound icon in your control panel to make sure that windows recongizes the sound card? If not, I'd check the easy stuff first. And if that doesn't work, you can find the drivers for that sound card HERE! Make sure that's the same version that you want.
